Abstract: FIRE HYDRANT LOCKING DEVICE   Abstract of the Disclosure A fire hydrant locking device is disclosed for pre-venting undesirable tampering, such as turning on the water release at the fire hydrant.  The device consists of an imper-forate dome encompassing and rotatably attached to a spider which in turn is secured to a know type of fire hydrant. Inside of the apex of the dome is a recess snugly fitting the nut which controls the opening and closing of the water supply through the hydrant.  The dome can be rotated, thus turning on the water, only by use of a special wrench which fits into receiving recesses formed on the outer face of the dome.

Title: Wood chip digester level control
Inventor: LOFKRANTZ JOHN E E

Granted: 1980-06-10
Abstract: ABSTRACT OF THE DISCLOSURE         A control system and a process is disclosed for a continuous wood chip downflow digestion system, The system maintains chip level in the top of the digester and maintains a consistency in the ratio of chips to liquor in the blowline thus allowing the system to run without constant operator attention.  The system comprises a means for measuring the level of chips at the top of the digester and producing a level index over a predetermined time.  This level index is compared with a preset level index and an error signal pro-duced which operates a speed control means within preset limits for a rotating scraper feeding into the blowline.          There is also provided a means for measuring the feed rate of chips to the digester, and a summating means for adding a predetermined ratio setpoint for the feed rate of chips against a flow in the blowline, to an integral of the error signal above or below a preset range to produce a summated ratio.  The blowline flow is then controlled within preset limits to proximate the summated ratio to the feed rate of chips.

Abstract: METHOD AND MEANS FOR REDUCING STRESSES IN DIE ASSEMBLIES     Abstract of the Disclosure A method and means for relieving unwanted tensile stresses in a die are disclosed.  The method involves steps of determining level of stress in critical regions of the die and then supporting the die in a way to induce counter-stresses that substantially eliminate unwanted tensile stresses therein during a forming operation.  A supporting means for reacting to the axial component of loads applied to the die cavity during the forming operation includes a supporting surface which is geometrically related to a contacting surface of the die to effectively reduce or eliminate tensile stresses during the forming operation.

Abstract: ABSTRACT OF THE DISCLOSURE      A lower frame member for supporting a pivoted sash of a window has two channel sections one above the other and communicating with each other.  The upper channel is open on top and becomes closed when engaged by the lower frame of a sash when the window is closed.  The upper channel communicates with the lower channel by vents in the bottom of the upper channel, the exterior side of the lower channel having a central passage which facilitates the axis to the pivot of the window for mounting, disassembling or servicing purposes.  The access opening at the same time provides communication with the exterior atmospheric air, whereby air pressure in an enclosed upper channel (with the window closed) is maintained at the same level as the exterior air pressure. The invention combines the advantage of facilitating access to the pivot of the window with an improved resistance of the window against leakage due to sudden increase in the exterior atmospheric pressure.

Abstract: CALIPER TYPE DISC BRAKE               ABSTRACT OF THE DISCLOSURE           A caliper brake having a brake disc rotatable about an axis with a friction lining carrier mounted for sliding movement axially of the brake disc on a supporting caliper housing.  The lining carrier has two circumferen-tially spaced ends with an opening at one end for receiving a torque pin mounted on the caliper housing for axial sliding movement of the carrier on the pin.  A slot is provided at the other end for receiving a retention pin which is mounted on the caliper housing for axial sliding movement of the carrier on the retention pin.  The retention pin is positioned in the slot with sufficient clearance to accommodate movement in the circumferential direction due to expansion and contraction of the carrier during braking.          The clearance between the torque pin and the opening in the lining carrier is only sufficient to prevent binding of the carrier on the torque pin and therefore limits the movement of the lining carrier in a circumferential direction while providing a sliding connection for axial movement of the carrier into and out of braking engagement with the brake disc.

Abstract: ABSTRACT OF THE DISCLOSURE                A thermal sill joint for separating the sills of interior and exterior metallic window frames is disclosed.  The thermal sill joint comprises a plastic hollow extrusion which is inserted between the two sills and sealed with sealing material.  The extrusion and the two sills have inter-engageable upper and lower flanges.  The lower flanges are inter-engageable by transverse downward movement of the extrusion relative to the sills, while the upper flanges are inter-engageable with a snap-action by moving the upper flanges of the sills towards the extrusion in a movement transverse to the latter.  Paste-like material seals the joint between the interfitting upper flanges.  It is possible to insert said sealing material, since it is not necessary to longitudinally slide the extrusion in position between the two sills.
